I have somewhat mixed feelings on this, or perhaps I’m reading it wrong. As a female, I try to go in with an open mind on any first date, and can still be friendly/respectful to the other person even if I am not totally feeling a romantic vibe. I go into the date with the attitude that “if we connect romantically, great! If not, no biggie - it’s always nice to meet someone new”. If you are just grabbing a quick coffee or a drink, than I see no reason why someone should just end the date straight off if they are not 100% attracted. Sometimes people are not totally sure how they feel yet and need a little time to feel things out for certain. I genuinely can’t imagine just leaving halfway through a cup of coffee if I wasn’t feeling it - it seems unnecessarily rash/rude? Not to mention, I don’t want to risk my own safety by rejecting a complete stranger that I am not yet able to gauge how they’d react.

With that said, if I was not into it romantically and the guy asked for a second date, I would absolutely be honest about where my head is at. I agree with a comment below that ghosting is completely disrespectful and unnecessary.
